The AM150175A from Polyphase Microwave is a Quadrature Modulator that operates from 15 to 17.5 GHz. It has an I/Q mixer, LO amplifier, I/Q lowpass filters, I/Q differential amplifiers and is ideal for direct conversion of baseband I/Q modulation to RF. The modulator has an output P1dB of -1 dBm, a conversion loss of up to 12 dB and an output noise level of -162 dBm/Hz. It has an amplitude imbalance of ±0.2 dB and a sideband suppression of -35 dBc. This modulator supports all bandpass RF modulation types including BPSK, QPSK, QAM, OFDM, AM, FM, PM, FMCW, and pulsed Doppler.
The AM150175A requires a DC supply of 5 V and consumes under 110 mA of current. It can be interfaced directly with single-ended or differential I/Q sources including most high-speed DACs. The modulator is available in a module that measures 64.24 x 64.24 x 12.7 mm with SMA-female connectors.
